Title : Meteor-M N2-2 Weather Satellite Updates: No More 137 MHz
LRPT, L/X-Band Working in Daylight
Content : In late December 2019 we posted about Russian weather
satellite Meteor M N2-2 which had unfortunately been struck by
a micro-meteorite on Dec 18, causing it to lose control and go
offline. Meteor M N2 and N2-2 satellites are often monitored with
RTL-SDR dongles as it is relatively simple to receive their LRPT
signal at 137 MHz which contains a high resolution weather satellite
image.
Title : Remote Spectrum Monitoring with OpenWebRX, RTL-SDR and the
Balena Cloud Service
Content : Thanks to Alan Boris of Balena.io for submitting their
new blog post titled " Running OpenWebRX on balena to remotely
monitor local radio spectrum ". Balena.io is an IoT cloud service
that is used for "building, deploying, and managing fleets of
connected Linux devices".
Title : PyPacket: An APRS iGate For Your RTL-SDR
Content : [ Pypacket ] was developed by GitHub user [ cceremuga ]
and allows you to take advantage of a Linux computer (such as a
Raspberry Pi) and an RTL-SDR to quickly and easily build your own
APRS iGate.
Title : Using a KerberosSDR to Monitor Air Traffic Control Voice,
ADS-B, ACARS & VDL2 Simultaneously on a Raspberry Pi 3B+
Content : The KerberosSDR is our 4-channel phase coherent capable
RTL-SDR unit that we previously crowdfunded back in 2018. With
a 4-channel phase coherent RTL-SDR interesting applications like
radio direction finding, passive radar and beam forming become
possible. KerberosSDR is currently available from the Othernet
store and Hacker Warehouse for US$149.95.
Title : Increasing L-Band Active Patch SNR by using it as a Feed
for a Satellite Dish
Content : Recently RTL-SDR.COM reader Bert has been experimenting
with our active L-band patch antenna product. He's written in
to share that he's found that using it as a feed for a satellite
dish works well to improve SNR on those weaker 10500 AERO signals
which Bert found that he could not decode from his location due to
insufficient SNR. Our active L-band patch antenna receives signals
from 1525 - 1637 MHz and can be used for signals from Inmarsat,
Iridium and GPS satellites.
Title : Measuring the Radiation Pattern of a Yagi Antenna with
a NanoVNA
Content : On Hackaday we've seen an interesting post about
Jephthai who has used a NanoVNA to measure the radiation pattern
of a home made Yagi antenna . He began by initially modelling the
Yagi using the MMANA software package, then building the antenna
and measuring the SWR.
Title : DSDPlusUI: A Graphical User Interface for DSD+
Content : Over on Twitter Annunaki (@StupotSinders) has been
teasing some screenshots of a GUI for DSD+ that he's been developing
over the past few weeks. And now he has released the software which
is called "DSDPlusUI". DSD+ is mostly command line based, so a GUI
could be useful for newbies. The software can be downloaded from
the DSDPlusUI groups.io page .
Title : A Guide to the NanoVNA: Kindle eBook for $2.99
Content : With the NanoVNA (and upcoming NanoVNA 2.0 ) being so
affordable and readily available many budget focused RF enthusiasts
and hams are now adding a tool to their arsenal that used to only
be for the wealthy and commercial users. Vector Network Analyzers
(VNAs) allow you to do things like make SWR measurements on antennas,
characterize RF filters and detect coax cable faults, among other
applications.
